Ayurveda, the Science of Life, traces back its origins to the Vedic ages in India. Considered a supplement to the Vedas, Ayurveda is a comprehensive system of health that focuses on leading a healthy life, helping an individual do his righteous duties (dharma), acquire wealth (artha) and gratification of desires (kama), and attain emancipation (moksha). For thousands of years, Ayurveda evolved through a process of scientific inquiry involving the loka (communities or societies). Within communities, scientific knowledge was created by an interchange of information between patients, physicians, and researchers. Teachers would pass their wisdom – updated with this scientific inquiry and application of their own learnings- to their students in an interactive manner, through what was called as the Guru-Shishya tradition. This knowledge was documented in the Brihatrayi , of which the Charaka Samhita is considered the most important and definitive. However, with time, Ayurveda went through its period of stagnation, or dark ages. There were no new updates or revisions to the Charaka Samhita, or any other Ayurvedic text, for centuries. With the advent of western scientific thinking with a greater focus on disease management and the evolution of modern medicine, Ayurveda was relegated to relative obscurity. Today, as leading thinkers are searching for more effective definitions of health, Ayurveda is again in the spotlight. The new edition of the Charaka Samhita, with updated inferences and applications, is one step in reinitiating that process of interaction between teachers and scholars, and helping thinkers in their quest for more effective solutions to problems of health.

The Treatise

As mentioned earlier, the Charaka Samhita is Ayurveda’s definitive treatise and the most referenced text of students, scholars, teachers, physicians and researchers of Ayurveda. As a text, the Charaka Samhita epitomizes one of the finest examples of classical Vedic teacher-student (Guru-Shishya) interactions ever recorded and written, either in ancient or modern times. Though literally meaning the “Compendium of Charaka”, it was actually not authored by Charaka, an ancient physician of renown. Rather Charaka redacted an earlier text called the Agnivesha Tantra, believed to have been written circa 1000 BCE by Agnivesha, a disciple of the legendary Vedic sage, Punarvasu Atreya. The term “Charaka” is derived from the root Sanskrit word, Char, or “move about”. There are no chronological records marking the evolution of the body of knowledge that is Ayurveda, but it is speculated that Charaka lived sometime in the 8th century, BCE, and a scholar named Dridhabala (300 CE) worked on to restore some lost portions of the text. In the last two thousand years, the popularity of Charaka Samhita spread beyond the frontiers of the Indian subcontinent, when it was translated into Arabic (8th century CE) and Persian (10th century CE). With the spread of Buddhism, it got translated into Tibetan and subsequently, Mongolian languages. Approximately 43 commentaries in Sanskrit were written through centuries – of which, Chakrapanidutta’s Ayurveda Deepika (or the Light of Ayurveda) is considered the most authoritative. In terms of its contents, while the Samhita addresses eight specialized branches of medicine, including Internal Medicine (Kayachikitsa), Supraclavicular/ENT (Shalakya), surgery (Shalya), toxicology (Vishagarvyrodhikachikitsa), (demoniac) seizures (Bhutavidya), pediatrics (Kaumarabhritya), science of rejuvenation (Rasayana), and science of infertility medicine and aphrodisiacs (Vajeekarana), it is Kayachikitsa that is considered the prime area of focus of the Charaka Samhita. In terms of its contents, it could have the unique distinction of being the only texts available worldwide on restorative science, emphasizing on the promotion of health and prevention of disease as the actual solution for controlling diseases, which is especially relevant in modern times. Further, it also seriously dwells upon the concept of longevity and healthy aging, as described in its chapters on Swasthavritta Chatushka and four padas of Rasayana Adhyayas. In terms of its structure, the Charaka Samhita consists of 120 chapters broken into eight sections, or Sthana. The text is written partly in the form of verses, or shloka, and partly in prose. In the last chapter of the last section of the Charaka Samhita (Siddhi Sthana, 12/52), it has been indicated that there are 12000 verses in the text. However, the extant versions of the treatise seem to have 8419 verses and 1111 prose paragraphs. Thus, some 2000 verses seem to have been lost in the course of its existence. The treatise’s first section – Sutra Sthana – lays the foundational principles of Ayurveda in 30 chapters. Concepts such as the mahabhuta (fundamental elements that make the human being as well as the universe around him, viz. earth, fire, air, ether, and water), doshas (body humors), dhatus (tissues), and other critical concepts have been laid here. The subsequent sections build upon the concepts laid in this section to explain human physiology, etiology of diseases, clinical sciences, etc. The final section is titled Siddhi, underscoring the key objective of the book – to help the reader attain emancipation through health. Quite like any body of scientific knowledge, the Charaka Samhita used to be a living document before it got into a “dark age” of relative stagnation. The world has changed since the originally redacted edition of the Charaka Samhita came about. A team of Ayurvedic scholars, biomedical researchers, modern medicine physicians, content managers, business consultants, and language editors have been working on a new edition of the Charaka Samhita. True to its tradition of a dialog between a teacher and a student, it is aimed to be a “living and interactive” text, planned and redacted online to allow for a broader outreach and to serve as an online source of reference on Ayurveda. The new Charaka Samhita has the same sequence of sections (and their chapters) as the original text (though a planned Uttar Tantra section would be added subsequently), with the same logical progression starting with the Sutra Sthana, covering the basic but generic principles of Ayurveda, right up to Siddhi Sthana, covering the specifics of Panchakarma.

  • Sutra Sthana (30 chapters) covers basic principles of Ayurveda with seven groups of tetrads (logical groupings of four chapters, or Chatushka) including medicaments (Bheshaja Chatushka), preventive and promotive medicine (Swasthya Chatushka), directions of utilizing Ayurveda principles (Nirdesha Chatushka), preparations useful for treatment (Kalpana Chatushka), Disease categories and classification of diseases (Roga Chatushka), Management principles of disease (Yojana Chatushka) and Dietary principles (Annapana Chatushka). The last two chapters are called Sangraha Adhyaya including important aspects of Prana (vital energy) and brief about the topics discussed in the entire Samhita.
  • Nidana Sthana (8 chapters) discusses the important clinical diagnostic tools for knowledge of disease as well as etiopathogenesis of eight major diseases.
  • Vimana Sthana (8 chapters) contains specific information about diet, dietary rules, epidemic diseases found in society, teaching and learning methods, various types of examinations and medical studies.
  • Sharira Sthana (8 chapters) describes details about the composition of the human body, its origin, the importance of body, mind and soul co-ordination, embryology & anatomical aspects of a human body.
  • Indriya Sthana (12 chapters) explains diagnosis & prognosis of disease with bad prognostic features and dreams on the basis of senses.
  • Chikitsa Sthana (30 chapters) gives treatment protocols and specific remedies for various ailments.
  • Kalpa Sthana (12 chapters) contains usage and preparation of medicine.

In the last century, modern medicine or allopathy has made significant strides in the area of disease management. However, in spite of the significant breakthroughs that it has witnessed, modern medicine continues to be primarily an offense strategy for managing ailments. The incidence of occurrence of disease continues to rise and healthcare costs are rising exponentially. It has become crucial to prevent the occurrence of diseases. Ayurveda primarily utilizes the defense strategy in health management as detailed and described in the treatise, the Charaka Samhita. Through the subsequent Uttar Tantra section, the new edition of the text will provide the clinician guidelines for using offense and defense strategies to win the war against human suffering from illness and create better health.

Thus, the new edition of the Charaka Samhita is a work in progress. It has four sections: 1. Sanskrit shlokas (verses) and transliteration into English 2. Translation from Sanskrit to English 3. Fundamental guiding principles, known as Tattva, are extracted from the treatise and recorded as inferences in Tattva Vimarsha. 4. Medical and surgical treatments and procedures change with advancements in science. Old treatments and procedures still effective are being retained and new ones are being added and commented in the Vidhi Vimarsha section. This section requires the help of specialists in various areas of health science. Currently Vidhi Vimarsha in most of the sections is either incomplete or absent and requires the help of volunteer scholars to complete. Future additional resources of the new edition of Charaka Samhita will include: 5. Video recordings of selected discussions between clinicians on the classic texts and their application in the modern world 6. A widely useful glossary of Ayurvedic terms in the biomedical language. 7. Illustrations will be added wherever necessary. 8. A recompiled Uttar Tantra section. The Uttar Tantra is thought to have existed and believed to have been destroyed or lost from the older editions of the Charaka Samhita. The newly introduced disease and their management, as well as modern terminologies for diseases enlisted in the Charaka Samhita, will be included. This section will be recompiled to contain modern treatment of diseases in which the offense/defense or Allopathy/Ayurveda strategy for better treatment of disease is utilized.
